A small amount of compressed air enters the annular chamber at point (A) that is then throttled through a small ring nozzle at high velocity and into the inside of the amplifier over a coanda profile. The compressed air stream clings to the coanda profile as it enters the inside walls of the amplifier and thereby creating a vacuum that induces the outside air at point (B) converting the pressure into amplified airflow. The amplified of airflow leaves at the exit at point (C). Airflow is further amplified downstream at point (D) by entraining additional air from the surroundings at the exit.
